new YORK, n. Y.. A CORPORATION OF NEW STRAND HOLDER.

Application filed June 21, 1924. Serial No. 721,381.

This invention relates to strand holders and more particularly to tape pad holders An object of the invention is to provlde a strand holder which will permit the ready removal of a tape pad or the like therefrom in a minimum amount of time.

Another object of the invention is to provide an improved strand holder from which a tape pad may be readily removed without distorting the tape or causing it to unwind. In accordance with the general features of the invention there is provided a strand holder comprising a head fixed to a winding arbor, a second head and a hub attached thereto, the head and hub being attachable to and detachable from-the winding arbor as a unit, the hub comprising a. split clock spring band, the ends of which are adapted to be spread apart or drawn together by means of two levers, secured thereto, Wl1lCl1 are actuated by a cam, latch means being provided for holding the removable head and hub on the winding arbor when applled thereto.

Other objects and advantages of the invention will more fully appear from the following detailed description taken in connection with the accompanying drawings which illustrate one embodiment thereof, and in which e Fig. 1 is an end elevation of the detachable portion of the strand holder;

Fig. 2 is a side elevation of the strand holder partly in section;

Fig. 3 is a vertical sectional view of the strand holder shown in Fig. 2 taken on the line 3-3 thereof showing the hub contracted;

Fig. 4 is a vertical sectional view taken on the line 4-4 of Fig. 1, looking in the dis rection indicated by the arrows, showing the complete strand holder applied to an arbor, and

Fig. 5 is a detail sectional view taken on line 5-5 of Fig. 2 showing the construction of the latch mechanism.

Referring now to the drawings in detail in which like reference numerals designate similar parts throughout the several views, denotes a winding arbor to which is se cured a head 11. Surrounding the arbor 10 is a similar head 12 which is spaced from the head 11 by a hub, denoted generally by reference character 13. The hub 13 comprises a split flexible band 14, (Fig.1) the ends of which are adapted to be spread apart or drawntogether by levers 15 and 16 respectively, secured thereto.

The lever 15 comprises an arm 17 (Fig.2)

extending from a hub 18 (Fig. 2) at one end, the other end of the arm being integral with a cross-piece 19 which is secured to one end of the band 14 by screws 9. Formed onthe side of the hub '18 opposite that side to which the arm 17 is secured is an arm 20 (Fig. 2) which has formed on its end an integral cross-piece 21. The lever 16 comprises two arms 22 and 23 (Fig. 2) formed on hubs 24 and 25, respectively. The. ends of the arms 22 and 23 are joined to-. gether by a cross-piece 26 which is secured to the other end of the split band 14 by screws 27. Formed on the side of the hubs 24 and respectively, opposite to that side to which the arms 22 and 23 are secured, are two arms 28 (Figs. 1 and 2) and 29. The ends of the arms 28 and 29 are joined together by a cross-piece 30 which is directly opposite the cross-piece 21 of'lever 15. The hub 18 is positioned intermediate the hubs 24 and 25 on a sleeve 31 which surrounds the arbor 10. The hubs being kept in place on the sleeve 31 by a ring orwasher 32 which is secured to the sleeve .31 by a screw 33.

The sleeve 31 is secured to the head 12 by screws 34 and 35 which are threaded therethrough into pins 36 and 37, respectively. The pins 36 and 37 are tapered and their ends are adapted to engage holes 38 and 39 in the head 11. (Fig. 2) these pins keeping the heads in a fixed position with respect to each other. The cross-pieces 21 and 30 of levers 15 and 16 respectively, are adapted to be spread apart by a cam 40 secured to a cam lever 41 which is journaled in the sleeve 31. Secured to the arm 17 adjacent the cross-piece 19 is a spring 42 whose other end is secured to the cross-piece 26 of the lever 16 intermediate the arms 22 and 23 (Fig. 2) thereof, the spring functioning to draw the two ends of the band 14 together. Formed in the sleeve 31 (Fig. 5) is a slit or hole 43 in which is located a latch 44, which is pivotally mounted 011 a screw 45. A knurled end 46 of the latch 44 is pushed outwardly by a spring 47 located in the sleeve 31 and end 48 of the latch 43 is adapted to be inserted into a groove 49 in the arbor 10. By

pressing on the end 46 of the latch 44, the end 48- is brought out of engagement With the arbor thereby permitting. the removal of the hub 13 and head 12 therefrom.

It is evident that by actuating the lever 41' the band let may be contracted or exp'andedi Normally when material is being wound on the hub 13 by rotating the arbor 10, the band 14 will be expanded, but upon removal of the hub 13 and the head 1-2 from the arbor 10 to permit the removal of the material t l iere-fron i, the lever 41 would be actuatedto contract the band let thereby permitting the material previously Wound to be very easily and readilyremoved.

The strand holder herein disclosed is particularly advantageous he takinglap-material'- in tape or other similar torn is,inasmuch the material Wound thereonv may be readily removed i n a minimum amount of time.

It is to be understood that the aboyc- (l-escribed strand holder may be modified in many respects WltllOllt departing from the spirit and scope of the invention and that the invention is to beli mi'te'd and restY-wtetl only by the appended claims.

lVh'at is claimed is:

1 In. a strand holder,- a winding arbor,- a head attachedthereto. a second head, and a l-i'ub intermediate said heads and secured to said second head, the lulbandthe second-- a head attached thereto. a second heacl and a hub intermediate-said headsand secured to said second head", the-hub ancbthe second head being attachable to and detachable from the Winding arbor as a unit, the hub comprising asplit band, and resilient means for drawing the ends of the band together.

3. In a strand holder, a Winding arbor, a head attached thereto, a second head, and a hub intermediate said heads and secured to said second head; the" hub and the second head being attachable to deta cl able from the Winding arbor as a unit, the hub comprising a split band, a pair of levers. a camfor actuating the pair of levers to expand the band, and resilient means for drawi'n g the ends of the- :hand together.

4;.
